CC -!- FUNCTION: Part of the ABC transporter complex PstSACB involved in
CC phosphate import. Responsible for energy coupling to the transport
CC system. {ECO:0000255|HAMAP-Rule:MF_01702}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + phosphate(out) = ADP + H(+) + 2 phosphate(in);
CC Xref=Rhea:RHEA:24440, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.3.2.1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01702};
CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins (PstB),
CC two transmembrane proteins (PstC and PstA) and a solute-binding protein
CC (PstS). {ECO:0000255|HAMAP-Rule:MF_01702}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01702}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01702}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Phosphate
CC importer (TC 3.A.1.7) family. {ECO:0000255|HAMAP-Rule:MF_01702}.
